so i have a 85 camaro that i bought a little while ago i just replaced the alternator because it was dead. the battery was not able to charge because of that. now tht new one is in and the battery is still not able to charge. i took it into get it tested at pep boys and they said it was fine. im woundering what the problem could be. could it be the wiring just draining the battery or the alterntor broke again or even the battery itself? please help!!!

First, start off with a fully charged battery. Take a voltage reading across battery terminals with engine running - If 11 - 12 volts at battery, alternator or wiring problem. If 13 - 14 volts at battery, alternator doing its job.
Again, with engine running, take voltage reading at large red ternminal at the back of the alternator. Report back findings & we'll go from there.

Another simple way to test the alternator is remove the positive lead from the battery while it's running. If it stalls the alt. is bad. If it stays running it's working.

It could be your starter causing the battery drain.

how could i tell if it is the starter? when the battery had a charge the car would run at high rpm's but if i let it idle then it would die

Im willing to bet its the wiring. Check and make sure all your wires are clean tight and insulated. Esepcially the starter cable, main ground and alternator wire. Dont make the mistake of throwing a lot of parts at it.
